That little plus sign…

October 6, 2017 – When we learn addition and get into regrouping, where we carry the tens digit of the sum from the ones column into the tens column, (a.k.a. “carry the 1”, even though it isn’t always a “1”), we just write that digit down and usually remember to add it to the original digits of that column.  However, when children are first learning this skill, I’ve noticed that sometimes they forget to add it.  So, what I encourage them to do is to put a little plus sign next to it, to serve as a reminder to include it in the addition.  It seems to make all the difference.   Perhaps it’s a subconscious thing, but whatever it is, I have seen it work.
